If the word that shall be displayed in bold text contains a
] you have to quote it with an exclamation mark to tell UDO
that it has to be printed in bold text, too.

When the last character is an exclamation mark, a / has
to follow or UDO would protect the closing bracket instead of
outputting an exclamation mark.

The HTMLversion of your source file will print the
descriptions in bold text, too, even if this not typical for HTML. The
next versions of UDO will offer a command to disable the bold text
inside descriptions for HTML.
